neovim-average-colorscheme.lua

-- "Average" color schemes
--
-- This script will load color schemes supplied in "Hyperparameters",
-- compute average color scheme (compute median attribute value of highlight
-- groups present in all color schemes) and save it under configurable name in
-- configurable directory.
--
-- Dependencies (ideally only these plugins should be loaded):
-- - https://github.com/echasnovski/mini.nvim/blob/main/readmes/mini-colors.md
--   (for color scheme manipulations)
--
-- - Reference color scheme plugins.
--   Supplied lists contain top 5 popular Lua Neovim color schemes. This is how
--   they were chosen:
--     - Go through https://github.com/rockerBOO/awesome-neovim.
--     - Pick top 5 Lua implemented color schemes with most stars which are
--       not repeating.
--
--     Final list (as of 2023-04-20):
--     | Color scheme                | Stargazers |
--     |-----------------------------|------------|
--     | folke/tokyonight.nvim       | 3476 stars |
--     | catppuccin/nvim             | 2639 stars |
--     | rebelot/kanagawa.nvim       | 2219 stars |
--     | EdenEast/nightfox.nvim      | 2055 stars |
--     | projekt0n/github-nvim-theme | 1379 stars |
--
-- Notes:
-- - Original list was made also accounting for Vimscript color schemes
--   with Neovim relevant highlight groups.
--   This included 'sainnhe/everforest' (1815 stars) as the fifth color scheme.
--   Although it is sooooooo nice, it is quite different in terms of which
--   attributes it defines for certain highlight groups. Including it instead
--   of 'projekt0n/github-nvim-theme' resulted in not very coherent output.
--   So in the end it was decided to take "top 5 **Lua** color schemes".
--
-- - Due to averaging colors using Oklab color space, sever disagreement on
--   some color attribute leads to its deasaturation (becoming more gray)
